5. Now we have two simple equations:
1) 100%=129000
2) x%=12785.57
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=129000/12785.57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 12785.57 is what percent of 129000
